As a PI user, I want to be able to visualize and analyze the SQC violations that are generated by the SQC rules.  The ability to save SQC outputs such as  Mean, median, mode, stdev, Cpk, max, min, 1-5 sigma zones, ucl, lcl in the follo...

KB00868 recommends Asset Analytics as the right job, but there are some major limitations that inhibit ease of use and deployment, specifically around operations on >1 attribute or tag simultaneously. To improve this, AF analyses functions th...

By now the NumOfChanges Function in AF Analytics does not take into account the value at the start of the timerange. NumOfChanges only counts the amount of changed values of the recorded values in the given timeframe. If I query the NumOfChanges ...

As a consumer of event frame data, I would like to be able to get a summary of the children event frame duration based on the trigger or severity over the duration of parent event frame when a parent event frame closes. The output should be stored...

I find myself making analytics on child elements which by themselves have limited value, but are needed to get rollup analyses to work. This adds complexity to the design of AF. Two ideas would improve this: 1) Count # of attributes that meet a c...
